Subject: [PATCH v2 0/4] vfio-mdev: Fix remove race,
 clean namespace and better define ABI

Cleanup the namespace a bit by prefixing structures with mdev_ and
also more concretely define the mdev interface.  Structs with comments
defining which fields are private vs public tempts poor behavior,
especially for an interface where we expect out of tree vendor drivers.

Additionally in v2, the patch removing the next field from mdev_device
is dropped, instead using it to fix a remove race, my From address is
fixed, and Documentation is updated.  Jike, I left your R-b on the
patches that didn't change only.  If I've missed any relevant doc
updates, please let me know.  Thanks,

Alex
